Description Clemens Eisserer 2011-05-14 13:58:16 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.2
Operating System: Linux 2.6.35.13-91.fc14.i686 i686
Distribution: "Fedora release 14 (Laughlin)"

-- Information about the crash:
- What I was doing when the application crashed:

I was moving a window from one virtual desktop to another.
These were exactly the steps I did:
- Clicked on the window-entry on the TaskBar plasmoid
- Grabbed (kept mouse button pressed) the window-entry and moved the window to the virtual desktop icon of the Pager plasmoid where I planned to move the window to.
Somewhere in between plasma simply crashed.


- Unusual behavior I noticed:

The crash can be reproduced some of the time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Aborted
